Stuart Progress Oscillating Engine. Pt 2 The Main Frame

I'm continuing with the Stuart Progress Oscillating Engine. A nice quick-ish build. Thanks to Sarah for the drawings she produced. They were a great help. The Home Model Engine Builders' Forum. Here's a link to Sarah's build. https://www.homemodelenginemachinist.com/threads/stuart-progress.36235/ Thanks to Bensound for the music. https://www.bensound.com/
